The reversible polydisperse Parking Lot Model
, 2003 We use a new version of the reversible Parking Lot Model to study the compaction of vibrated polydisperse media. The particle sizes are distributed according to a truncated power law.

Optical polarization of localized hole spins in p-doped quantum wells
, 2011 The initialization of spin polarization in localized hole states is investigated using time-resolved Kerr rotation. We find that the sign of the polarization depends on the magnetic field, and the power and the wavelength of the circularly polarized pump

Initial Events in Bacterial Transcription Initiation [PDF]
Biomolecules, 2015 Transcription initiation is a highly regulated step of gene expression. Here, we discuss the series of large conformational changes set in motion by initial specific binding of bacterial RNA polymerase (RNAP) to promoter DNA and their relevance for regulation. Bending and wrapping of the upstream duplex facilitates bending of the downstream duplex into

Color image segmentation using a self-initializing EM algorithm [PDF]
, 2006 This paper presents a new method based on the Expectation-Maximization (EM) algorithm that we apply for color image segmentation. Since this algorithm partitions the data based on an initial set of mixtures, the color segmentation provided by the EM ...

Diversity of Stratospheric Error Growth Across Subseasonal Prediction Systems
Geophysical Research LettersThe stratosphere has previously been shown to be a significant source of subseasonal tropospheric predictability. The ability of ensemble prediction systems to appropriately exploit this depends on their ability to reproduce the statistical properties of

Teachers’ perceptions of their own initiative: Collective initiative vs. personal initiative [PDF]
Zbornik Instituta za pedagoska istrazivanja, 2013 Current trends in education demand from teachers to exhibit proactive behaviour and assume responsibility for the implementation of changes in school practice. In that sense, it is important to study how teachers perceive their own initiative and to gain insight into the activities where such initiative is demonstrated.
